Slide-N-Size is a portable tool used to size latex balloons from 1.5-inches to 36-inches (4 cm to 91 cm). The metal ruler base can be folded for compact use and fits into a sleek protective tin container.

The ruler can be extended for larger balloons. Pole extenders are also included to size jumbo balloons– simply turning the poles to create any size template. To inflate a balloon with air or helium­– fill the balloon and then let out the gas until the balloon diameter matches the template.

Size one balloon to a diameter of 1.5-inches to 18-inches: Insert the folded metal ruler into a foot and line up the holes and then screw a sizing pole in. Slide a second foot onto the ruler, so the left edge lines up with the desired size. Lock it in place with another pole, and if you need a new size– just turn the pole, slide the base, and re-lock. Then inflate a balloon with air or helium, then let out gas until it just touches the poles.

Size two small balloons at the same time: Slide the third foot onto the folded ruler so the distance between the feet is the same. Secure it with the third sizing pole. Inflate a balloon in each hand, and again let out air until they just touch the poles. 


Size two balloons of different sizes: Unfold the ruler and then set up the three feet and sizing poles at the desired size and repeat the steps above. You can size the balloons together, or alternate without resetting the sizer.


Size one balloon up to 36-inch: Unfold the ruler and set up with the three feet and two sizing poles. Place the pole extenders over the sizing poles to lengthen them.
